Boasting the most powerful engine in its class, a composite hull that offers sporty handling, plenty of rider-friendly features, and serious value, the Jet Ski® STX®-15F will have you looking for reasons to get out on the water more. It’s the perfect personal watercraft to complement all your summer fun.

160 horsepower* 1,498cc Engine
• Four-stroke engine provides incredibly strong low and mid-range torque
• The most powerful engine in its price range
• Dual overhead cams (DOHC) are light and compact for less valve train inertial mass
• Large valves provide better intake and exhaust flow to improve torque and power
• Intake and exhaust valve lift, as well as cam timing, are optimized to reduce exhaust emissions
• Large capacity airbox cuts down engine noise and provides good air intake flow
• Intake tract designed for maximum performance
• Digital fuel injection provides great throttle response, smooth engine performance, quick acceleration, easy starting and excellent fuel economy
• Tip-over protection shuts engine off if craft tilts more than 61 degrees
• Waterproofed ECU and ignition coils protect the ignition system from electrical shorts
• Unique semi-dry sump oil system lowers the crankshaft in the engine, eliminates the need for scavenging pumps, and keeps the oil from flooding the crankcase if the craft is capsized
• Kawasaki’s patented oil separator provides fail-safe venting for the crankcase and prevents oil from flowing into the intake tract if the craft is capsized
• Has earned a Three-Star Ultra-Low Emissions rating, meets the Environmental Protection Agency’s strictest standards, as well as the California Air Resources Board’s standards *Horsepower measured in PS at the crankshaft under controlled conditions. Actual performance may vary.

Steering System
• Kawasaki Smart Steering® (KSS®) monitors steering input and engine speed and, when certain conditions are met, raises rpm to give enough thrust to maneuver
• Reverse bucket is designed for more precise direction control when backing and is made of injection molded material to prevent corrosion
• Reverse increases maneuverability in tight places

The JET SKI® STX® packs nearly 40 years of Kawasaki JET SKI and Ninja® performance know-how into a highly advanced, ruggedly reliable craft that delivers an unbeatable performance-to-price ratio. Though it leaves off a few non-essential items to keep the price down, the STX is still packed with all sorts of good things, like Smart Learning Operation (SLO), Kawasaki Smart Steering® (KSS®) and, oh yeah – a 1498cc four-stroke four-cylinder engine that’ll leave other PWCs in its price range sucking wake. Big power and great handling are definitely part of the package.

Safety and Reliability

• Tip-over protection shuts engine off if craft tilts more than 61°
• Smart learning Operation (SLO) mode limits maximum engine speed, when the SLO key is used
• Waterproofed ECU and ignition coils protects the ignition system from electrical shorts
• Unique semi-dry sump oil system lowers the crankshaft in the engine, eliminates the need for scavenging pumps, and keeps the oil from flooding the crankcase if the craft is capsized
• Kawasaki’s patented oil separator provides fail-safe venting for the crankcase and prevents oil from flowing into the intake tract if the craft is capsized
• Shielded jet propulsion system offers greater protection from damage
